Dell EMC Avamar 19.7 Release Notes

Sybase ASE plug-in known issues

The following table lists the Sybase ASE plug-in known issues in this release:

Table 1. Sybase ASE plug-in known issues
Issue ID Subject/Functional area Description Workaround/Resolution
286467 Known problem in Oracle, DB2, and Sybase plug-in for snapview failures When a backup is initiated from the Avamar Administrator and fails in the late stages of the backup operation, it is possible that the plug-in application considers the backup to be successful. You cannot perform a restore operation on this backup from Avamar Administrator. Restoring such a backup, though not possible through the Avamar Administrator, may still be possible by using a command line restore. This step is documented as a supported operation in the Sybase Plug-in user guides.

How to identify the issue:

  1. The database reports the backup as successful, although the Avamar Administrator reports it as failed.

  2. Failed backup log messages include an error message that is generated during the late stages of the backup.

    • For the Avamar Plug-in for Oracle, DB2, and Sybase ASE, the failure is logged with the error message: Failed to create the snapview. However, the database data has been successfully backed up and is marked as a hidden backup. Restore is available through CLI only. See the plug-in documentation for information about restoring hidden backups.
    • In the case of an incremental backup, the failure is logged with the error message: If a transaction log truncation was performed during an incremental backup of a Sybase database with the data and log on separate devices, the transaction log is now at risk of being lost. Perform an immediate full backup of the impacted database to protect the data. Consult the Avamar Plug-in for Sybase documentation for more information.
NOTE Best practice is to monitor all backup failures and ensure that such cases are followed with a successful full backup. This step requires that you create a successful full backup after any failed backup event.
